What is a fat quarter? A fat quarter is what you would get if you took a regular one yard cut of fabric and cut it in half both length-ways and width-ways to make 4 nearly square pieces. Commonly used with pretty printed cotton fabrics for quilting and crafting, if the fabric is 44 inches wide and 36 inches long in a yard, then a fat quarter measures 22 inches by 18 inches. It is an economical way to buy a more expensive fabric and perfect for making quilting patterns, or for small crafting items like this bag where the rest of the fabric would perhaps go to waste. And the Buttercup bag pattern has been drafted with this in mind to use a fat quarter of fabric to the best effect.
